After upgrading the backup server from version 6 to 8.1 or above, how to perform a single backup set rebuild for legacy backup set that was created in version 6, if the client application is not upgraded?

Steps:
To run a single backup set rebuild, login to the AhsayCBS console, select Users, Groups & Policies:

1. Select the corresponding backup account, then Backup Set.
   
   
2. Select the corresponding backup set, then click Destination.
   
   
3. Under Standard Destination, beside the CBS Destination Storage, click on the Rebuild button.
   
   

To run a user rebuild for a single or multiple users, select Users, Groups & Policies:

1. Under Backup User, select the check box beside the backup account(s) that you would like to perform a backup set rebuild for.
   
   
2. Click on the Rebuild Storage Statistic button (right most circular button under Manage Backup User):
   
   

Note: Note that a backup set rebuild can only be started when there is no backup job running (of the corresponding backup set), and vice versa.

The time taken to complete a rebuild depends on number of factors such as the number of files / folders in the backup set(s), the number of backup sets, the hardware specifications of your AhsayCBS server such as the disk I/O and CPU performance, and if there are other resource intensive jobs running.


To check the progress of a backup set rebuild you can go to AhsayCBS console, select Backup / Restore Logs:



Select Activities Log, when the rebuild job is started the following log entry can be found:

Timestamp	Login Name	Owner	Type	Message
	...	...	...	...
YYYY-MM-DD hh:mm:ss	username		RoutineJobInfo	Rebuild-username Starting single user rebuild

When the rebuild job is completed, the following log entry can be found:

Timestamp	Login Name	Owner	Type	Message
	...	...	...	...
YYYY-MM-DD hh:mm:ss	username		RoutineJobInfo	Rebuild-username SingleBackupSetRebuild Finished single backup set rebuild.
